Hydra Slayer is a Roguelike game focused on one thing: slaying Hydras. It is inspired by Greek mythology, Dungeon Crawl, MathRL seven day roguelike, and some mathematical puzzles about brave heroes slaying many headed beasts.

You are facing a nine-headed hydra. Your flaming longsword cuts five heads in each swipe (no more, no less), which will kill a five-headed hydra, but a larger hydra will regrow two heads after each swipe. Your storm scythe cuts exactly seven heads, but it makes ten heads grow back if the hydra is not dead. Is it possible to kill the hydra? What if you also had a silver dagger, which cuts just one head, but makes five heads grow back?
